able means such as the plug 16 having a split shank portion 1'? resiliently engaging the sides of the opening. During the rotation of the roller, as will be later described, lubricant from the cup, which may be filled to the level indicated at 17 finds its way between the surface of the shaft 6 and the hub 13, bycapillary attraction, and then flows out between the flange 11 and the por tion 18 of the supporting bracket with which it contacts. :ltlis important that a heavy lubricant such as heavy oil orgrease shall be used, otherwise the lubricant find.

ing its way to the top of the roller is apt to be throwncout by centrifugal force from beneath the engaging portion 18 of the supporting bracket,

Between the flanges 11 and 12 of the various rollers is supported in the same plane therewith and engaging their peripheral faces the ring traveler indicated at 20.

a n n This traveler is of substantial weight, a

traveler five inches in diameter weighing approximately a half a pound. As shown three supporting rollers 10 are employed equi distantly spaced angularly about the periphery of the ring traveler 20 and furnish the solesupport therefor. it will be noted that the rollers 10 are of considerably smaller diameter than the ring traveler. They therefore act to permit rotation of the ring traveler to be initiated readily but when the ring traveler is up to speed, the

five inch traveler rotating, say, 1500 R. P. M, the extremely high peripheral speed of the comparatively large ring can not be attained by the small diameter rollers 10 since this would require an extremely high. angular velocity for these rollers which it is impossible for them to reach. They therefore imparta frictional drag to the rotation of the traveler at this high speed which imparts a tension to the yarns so as to cause proper twisting thereof, the parts being preferably so designed and proportioned that the retarding effect from this cause is sufficient for the lighter and weaker yarns. Adjacent each. roller 10 the upper face of the support 1 is formed with an arcuate groove 21 for the reception of dirt or other foreign matter which may be removed from the ring by the action of the rollers thereon) This groove 21 communicates with a downwardly inclined passage 22 which extends on either side of the oil cup 1 and opens outwardlyof the lug 2 as at 23, thus furnishing an escape for such foreign mat ter outwardly of the ring support.

For working on-heavier yarns where a heavier tension must be employed, provision is made for imparting an additional drag to the rotation of the traveler. One form of this mechanism is illustrated in Figures 1, 2, and 1 and comprises an are shaped brake member 25 having upperand lower guide flanges 26 spaced apart a sufficient distance to permit the ring to rotate freely therebetween. This brake member 25 is lined with a frictional material such as leather, as shown at 27, which may engage the outer face of the traveler. F or the purpose of supporting the. brake in position relative to the trayeler 2 a pair of adjacent outwardly extending lugs may be extended toward each other as shown at in Figure 1, the top faces of these extensions forming supports on which end extensions 31 of the brake member 25 may ride. In order to provide for adjust ably applying pressure to the brake mem ber 25 to force it against the ring, means such as is shown in these figures may be employed comprising a :sprlng bar 35 1 threaded on the screw 39 and having anactuating disk or head 42 thereon preferably 7 of slightly larger diameter than the head d0 to permit it to be readily actuated by the operator. By adjusting the position ofv the screw 39 relative to the spring35 more or less pressure maybe exerted against the brake 25 to thus apply more or less drag to the rotation of the ring traveler in addition to that caused by the small rollers 10. lVhile one brake only is shown a plurality of brakes spacedabout the periphery'of the ring1 might, of course, be employed if desire ures 6 and 7 and in which a brake element 50, flanged to project above and below thering traveler is provided with a boss 51 perforated to receive a-rock shaft 52 carrying at its upper end a head 53 by which it may be turned,rthis head restingon the upperface of the boss 51. The lower end of this rock shaft is of reduced diameter as shown at 5 1, this portion being arranged eccen-- trically to the remainder of the shaft. This portion is journaled in an eye 55 at one end of a leaf spring 56 which is made fast at its other end as at 57 to the support 1,. By turning the'head 53 the effective connection of the spring to the brake member 50 may be adjustedto and from the ring traveler so that the spring may press with a lighter or Another form of brake is shown in Fig- 7 heavier pressure thereon and consequently adjust the retarding effect produced by the brakes A set screw having a knurled head shown at 58 passes through the boss 51 and engages the rock shaft 52 to fix the parts in any adjusted position.

In Figure 8 a further modification is' shown in which the frictional face of theand 71, each formed of a wire or pin having a reduced extremity as at 72 extending through perforations 73 spaced apart both horizontally and vertically in the inner face of the ring 20. These hooks 70 and 71 face each other, their free ends extending in opposite directions closely spaced past each other and being brought into close proximity with the inner face of the ring at the points 74 beyond which they are outwardly turned as at 7 5. The yarn may be readily placed in position through the eye thus formed by bringing it first under the end 7 5 of the lower hook member, moving it toward the central port-ion of the member and then bringing it over and putting it under the end 75 of the upper hook and then bringing it to the central position where it passes through the vertical opening '7 6 defined by the two hook elements and the inner face of the ring. The elements 70 and 71 lieentirely between the planes of the upper and lower faces of the ring and hence are not liable to cause in ury to the operators fin-' gers since they are entirely out of the way. i

The construction also is readily threaded and when once threaded the yarns can not; become accidentally unthreaded duringfthe spinning or twisting operation. c
